Frequent Questions

Is sulfur measurement at 15 ppm level practical at the pump? Do any of these methods work for portable/field testing?

Currently only for sampling at the pump and testing in the lab. However, a portable MDWXRF instrument (ASTM method D 7039) is being considered for field testing use.
